| Popis: | Three monomers of maleic anhydride (MAH), methyl methacrylate (MMA), and butyl acrylate (BA) are graft copolymerization of high-density polyethene (HDPE) by grafting and melting grafting method to prepare the graft copolymer as an interfacial modifier. The results of infrared spectroscopy (FTIR) showed that we graft polar monomers onto the chain of polyolefin molecules. The modifier HDPE-g-MAH/MMA/BA (M-GPE) is successfully prepared by the melt grafting method. Secondly, the wood flour and bagasse are pre-treated by steaming and boiling. We found that cooking could improve the mechanical properties of wood flour and bagasse, and the mechanical properties of cooked wood were higher than that of steamed wood. Finally, we use the melt grafting method to modify polyethene wax (PEW) and obtain PEW-g-MAH/MMA/BA (M-GPEW). M-GPEW and MGPE are used together to improve the interfacial compatibility of pre-treated wood plastic composites. The results show that the optimum ratio of the compound modifier M-GPE/GPEW is 8/2, and the mechanical properties of the material are the best. The mechanical properties of the wood-plastic composites are much more affected than the single modifier. |
